Internal Control Registers
4.1
Overview
The decoder is initialized and controlled by a set of internal registers which set all device operating
shows the summary of these registers. The reserved registers must not be written. Reserved bits in the
defined registers must be written with 0s, unless otherwise noted. The detailed programming information
of each register is described in the following sections.
I2C register FEh controls which of the four decoders will receive I2C commands. I2C register FFh controls
which decoder core responds to I2C reads. Note, for a read operation it is necessary to perform a write
first in order to set the desired sub-address for reading.
Compared to previous video decoder, TVP5154A, the TVP5156, TVP5157, and TVP5158 add decoder
auto increment and address auto increment bits control. If decoder auto increment bit is set, the next
read/write is from/to the next decoder that is enabled. If address auto increment bit is set, the address will
increment after all the decoders enabled read/writes are completed. The detail of I2C registers FEh and
FFh is shown in their register section.
